A video stream load balancing method and device

Abstract

The invention relates to a video stream load balancing method and a video stream load balancing device, which are used for receiving video streams and analyzing to obtain control signaling of the video streams; Counting the current video load values of one or more security isolation devices of the network; Selecting a current optimal network security isolation device; For the preferred network security isolation equipment, the RTP real-time streaming media service is redirected to the preferred network security isolation equipment; The preferred network security isolation device performs a video stream data isolation exchange service. The beneficial effects of the invention are as follows: the paint has good effects; through video control signaling analyzing, a network security isolation equipment load calculation and video stream redirection method, Video stream load balance in a network isolation environment is realized, dynamic distribution of video isolation and exchange capacitiesof a plurality of network security isolation devices in the network isolation environment is realized, and a transparent, low-delay and low-load network security isolation device video stream accesschannel is provided for a video client.

Description

technical field [0001] The invention relates to a video stream load balancing method and device, belonging to the field of communication and computer. Background technique [0002] At present, with the rapid development of technologies such as big data and Internet services, it has become a very common network security solution to use network security isolation equipment to realize cross-network information security exchange under TCP / IP network isolation environment. In industries such as transportation and energy, network security isolation equipment is widely used to realize network isolation between video surveillance network and departmental intranet. Intranet clients use network security isolation equipment video proxy service to realize video stream access under network isolation environment. [0003] Generally speaking, it is to estimate the concurrency of client access to video, and calculate the total data bandwidth according to the video stream bandwidth of differ...

AI Technical Summary

Problems solved by technology

[0004] When a single network security isolation device cannot meet the bandwidth requirements of video access, and multiple network security isolation devices need to be deployed, some network security isolation devices may be congested due to random access to the network security isolation device by video clients. Downtime, some network security isolation devices are idle, and resources are not fully utilized
